Resumo
This paper proposes to model, design and
implement a LCC (Line Commuted Converter) for power
generation purpose, using alternative sources such as
photovoltaic panel (PV), fuel cell and permanent magnet
synchronous machine as the main power source. The
converter is built with a full bridge twelve-pulse thyristor
topology and connected to the alternative source through
a line reactor. In order to extract maximum power from
the sources, a classical maximum power point tracking
algorithm (MPPT P&O) is applied. To validate the
theoretical and simulated analysis, a 600 W experimental
setup was built and controlled in closed loop. For the
experimental results, the alternative source was
represented by a variable DC power source in series with
a resistor, making it possible to create controlled power
steps and power events. During the operation, the grid
current is analyzed in terms of power quality and an
islanding event was created to analyze the converter’s
behavior under critical conditions. All the experimental
results show perfect conformity with the theory and
simulation, proving the effectiveness of this converter
topology for this purpose.
